Seeing that I live in Speedy and recently found I have that weekend off work I might be able to attend for part of the weekend. I will not be able to know for sure until the date is near. I would not need to camp out there anyway.
If you guys are short of land to shoot on or are looking for permission you might want to try this idea: The local AM country radio station is often littered with radio ads looking for people to come and shoot gophers on their land. Some even offer food and bullets if you come and shoot on their land. The radio classifieds are called the trading post and it is a 30 miniute live show from 11:30 am to 12 noon weekdays on CKSW. A quick web search will lead you to their website and you can email or fax an advertisement into the radio station, or call in at that time if you want to be heard on the radio. You may want to consider a day trip to the Pontiex area, they are plagued there.
The Co-oP here in the Swift Current Mall often has the best prices on Federal rimfire ammo. As mentioned before Walmart, Canadian tire and Bender's Gun and Archery (still not recommended) are the other sources. If any of you guys are travelling down through the Leader area there is a good shop up there as well, Doug Rayner is the guys name and he is in the book.
And for you guys that were silly enough to post pictures of your ammo stores, not even close... I went out on Monday and it was really windy. The gophers did not seem to mind, it was hot out anyway. I went out after lunch, shot 300+ rounds through the 17HMR and 300 rounds through the 223. I had to come home early because I ran out of ammo. The gophers stood atop the hill and laughed in a victorious ceremony as I left the warfield. I was probably only hitting 50% with the 17 because of the wind but hitting well over 90% with the 223.
